• 2. Two-arm monopole antenna with a CPW feed
• The antenna has the similar features to Antenna 1
  except for .using a co-planar waveguide (CPW)
  feedline

• 1. Two-arm monopole antenna with a microstrip
  feed
• A monopole antenna, composed of two metal strips
  and a microstrip feedline and printed on an
  FR4/Epoxy substrate, is proposed for WLAN
  applications
• The antenna has characteristics of low-cost,
  low-profile, small size, omni-directional
  radiation patterns and easy to be integrated with
  the associated circuits

Operation bands 2.4 GHz and 5 6 GHz
Far-field Patterns at 2.45 GHz
Far-field Patterns at 5.2 GHz
Operation bands 2.4 GHz and 5 6 GHz

• 3. Three-arm monopole antenna with a microstrip
  feed
• Additional metal strip is added to Antenna 1 to
  generate the third operation band shifting
  between 1.7 GHz and 2.0 GHz for the DCS1800 or
  PCS1900 systems

• 4. Diversity antenna PAIR based on two-arm
  monopole antennas
• Two Antenna 1 are arranged orthogonal to each
  other in space to achieve space diversity,
  pattern diversity and/or polarisation diversity

Operation bands 1.85 GHz, 2.4 GHz and 5 6 GHz
